添加记录到ds保存到xml
DataSet ds = new DataSet("myDs");
//从XML中读取数据
ds.ReadXml(Server.MapPath(@".dbdbGuest.xml"));
//以下为添加记录
DataRow dr = ds.Tables[0].NewRow();
dr["Name"] = tbName.Text.Trim();
dr["City"] = tbCity.Text.Trim();
dr["Email"] = tbEmail.Text.Trim();
dr["Message"] = tbComments.Text.Trim();
dr["STime"] = DateTime.Now.ToString();
ds.Tables[0].Rows.Add(dr);
//写回XML
ds.WriteXml(Server.MapPath(".\db\dbGuest.xml"));
用ds显示xml
DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath(@".dbdbGuest.xml"));
dgShow.DataSource = ds.Tables[0].DefaultView;
dgShow.DataBind();
xml添加到ArrayList
<?xml version="1.0" encoding="utf-8" ?>
<PEOPLE>
<PERSON>张三</PERSON>
<PERSON>李四</PERSON>
</PEOPLE>
XmlDocument doc = new XmlDocument();
